EYE PROTECTOR.

Application filed July 30,

The present invention relates to an improved eye )rotector and to theprocess for forming the same. I

An important object of the invention is to provide an eye protectorhaving particular reference to a curved auto goggle, wherein a lens maybe associated with an eye cup in such a manner that it will be held inposition when in use, while at the same. time it may be easily andconveniently removed when desired.

Another important object of the invention is to provide an eye protectorof this character which will be exceptionally light, thus permitting itsuse for a long time without causing any discomfort to the user.

Another important object of the invention is to provide a goggle of thisnature, and process of forming the same, whereby such a goggle can bemade much more inexpensively than has heretofore been done because ofthe fact that less material is wasted and that the manner of manufactureis reduced to the simplest way possible.

Other objects and advantages of the invention will become apparentduring the course of the following description.

In the drawings, wherein like numerals are employed to designate likeparts throughout the same:

Figure 1 is a front elevation of a pair ofgoggles constructed inaccordance with the present invention Figure 2 is a fragmentaryperspective view of the goggle illustrating the lens par tially inposition.

Figure 3 is a similar view showing the lens locked in position for use;

Figure l is a fragmentary sectional detail showing one manner ofmounting the lens;

Figure 5 is a similar section showing a slightly modified form;

Figure 6 is a view of the construction shown in figure 5 after the lenshas been fastened in position;

Figure 7 is a top plan of another form of goggle.

In the drawings, wherein for the purpose of illustration is shown thepreferred em bodiment of the invention, the numeral 10 designates agoggle in its entirety, which comprises the cups 11 having the lenses 12therein, the said cups being connected together by a bridge portion 13and having 192%. Serial No. 729,086.

a head band 14 for holding the same in use uponthe head of the user whendesired.

This particular type of goggle is designed for use particularly as anautomobile and motorcycle goggle, and to this end a form of goggle isconstructed that will give a large field to look through so that thegoggle will not hinder the user when in actual use.

l 'he cups in the present instance are preferably formed from a singlelength of material 15 as shown in Figure 2, the said material beingperforated as at 16 for the purposes of ventilation, and having theslots 17 therein to permit of the connection of the bridge portion 13.Prior to the formation of the strip into the form of a'cup,vit issuitably out out to form the curved edges 18, which edges are so formedas to fit snugly against the face of the user without any discomfort tothe user. After the strip 15 has been shaped and perforated asdescribed, it is bent, preferably into the form or shape of cup as shownin Figure 1. The ends of the strip overlap, as at 19, and are heldtogether by means of rivets 20, which rivets have the rounded heads, asclearly shown in Figure 2, projecting on the outer surface of the cup.The lens may be held in the cup in one of two ways, that is, as is shownin Figure 2 and a, by forming a groove 21 in the two sides and nose endof the cup, having the outer end reduced so that a lens 22 can beinserted in the groove 21, as is clearly shown. A pivoted latch member23 is connected to the cup by the pins 2d, and is provided with thedetents 25 so that when the latch 23 is swung into operative positionthe detents 25 will engage the rounded head of the rivets 20, thuspreventing accidental displacement of the catch and holding the lens inpositionw In the other case the lens 22 is placed in the cup, as shownin Figures 5 and 6. In this instance an offset portion 26 is providedand after the lens has been placed in position, as in Figure 5, theoffset portion is rolled over the lens to form the head 27.

I preferably form the eye cups from a cellulose composition material sothat the cups will be light and also for the reason that the cellulosecomposition material can be made transparent, thus permitting of a lightconstruction containing a lens, while at the same time it does not inany way-cut off or interfere with the natural vision of the user. Thus,in the instances where a cellulose composition material is used, when itis desired to remove the lens from the head 27, it is merely necessaryto heat the cup and the bead can then be rolled back, the lens removed,and a new one rqalaced.

Attention is called to the fact that a considerable amount of materialand time is saved in constructing the cup from a strip of material whichis perforated, grooved and shaped prior to its formation into the cup,while at the same time the round headed rivets Q0 serve a dual function,namely, they act to hold the interlappii'ig ends 19 together and formmeans to engagethe pivoted latch 23 to prevent displacement of the latchwhen the lens 22 is in position and the latch swung down for use.

The cup can be shaped in any desired manner and can be of anyconfiguration, as will readily be understood.

It is to be understood that the form of the invention herewith shown anddes tribe-d is to be taken as the preferred embodiment of the same, andthat various changes in the size, shape and arrangen'ient of parts maybe resorted to without departing from the spirit of the invention or thescope of the subjoined claims.

Having thus described my invention, I claim:

1. An eye protector of the class described, comprising a pair of lensholding frames, each of said frames being formed from a length ofmaterial, the ends of which overlap, means to hold the ends together,and a pivoted catch engageable with the said means when in operativeposition.

2. An eye protector of the class described, coinprising a pair of lensholding frames, each of said frames being formed from a length ofmaterial, the ends of which overlap, means passing through the said endsto hold them together, and having knobs carried thereby and a pivotedcatch carried by the frame and engageable with the said knobs to holdthe same in operable position.

An eye protector of the class described, comprising a pair of lensholding frames, each of said frames being formed from a length ofmaterial and having overlapping ends, means to prevent separation of theends, and having knobs thereon, a pivoted catch carried by the frame andengageable with the knobs to hold the same in operative position, thesaid frame having a lens receivng groove formed therein.

41-. An eye protector of the class described, con'iprising a pair oflens frames, each of said frames being formed from a length of cellulosecomposition material, the ends of which overlap, means passing throughthe ends to prevent separation thereof, knobs :arried by the said meansand a pivoted catch carried by the frame and having a portion engageablewith the said knobs to hold the same in operative position.
